Title: Optical coupler and apparatus associated with the same
Inventor: GOTO HIDEO
IPC: H01L31/12
Filed: 1989-12-28
Abstract: PURPOSE:To abruptly reduce an interference between devices using drive power sources by non-commonly using the group of the drive power source of a liquid crystal for forming an optical coupler and the ground of a drive power source of a light emitting element and a photodetector. CONSTITUTION:An apparatus 100 has a liquid crystal driver 102 and an IC device 104. The ground 106 of a drive power source V1 of a liquid crystal driver 103 for forming the driver 102 is insulated from the ground 108 of a drive power source V2 of the device 104. A liquid crystal device 14 is controlled by a signal from the driver 103, the quantity of light received by a photodetector 12 is altered, a current responsive thereto flows to a resistor R1 to introduce a control signal to a relay in the device 104 from an output terminal 1. In this case, power consumption of a liquid crystal driver 192 is alleviated. In other words, since noise component to be fed from the device 104 to a ground line is eliminated, the erroneous operation of the driver 102 can be abruptly avoided.

Title: Elctroplating pretreatment liquid for titanium and electroplating pretreatment method using the liquid
Inventor: OKADA TAKASHI
IPC: C25D5/38
Filed: 1999-12-02
Abstract: PROBLEM TO BE SOLVED: To obtain a high adhesion property to an electrodeposition film by a short-time treatment to a titanium base metal surface and to develop the pretreatment liquid having excellent stability with lapse of time. SOLUTION: This electroplating pretreatment liquid for titanium contains a water-soluble oxidizing agent, such as hydrogen peroxide, a water-soluble complexing agent which is at least one kind of compounds selected from the group consisting of polyamines, oxycarboxylic acids, aminocarboxylic acids, phenols, ascorbic acids and polyphosphoric acids and a base and is prepared to neutrality or alkalinity. The oxidizing agent, such as hydrogen peroxide, acts in the state that the titanium complexing agent is complexed to titanium ions and therefore the adhesion of hydrate to the titanium base metal surface and the generation of precipitate in the liquid do not occur and the adhesion property to the electrodeposition film in electroplating increases effectively. Since the generation of the hydrate may be suppressed, the stability of the pretreatment liquid with lapse of time is good.

Title: Optical reproduction device
Inventor: JINNO MASAHIKO
IPC: H04B10/588
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To reproduce an optical signal waveform and to improve the S/N without reproduction processing of an electric area by providing a nonlinear characteristic to the modulation efficiency and modulating and outputting a continuous light from a continuous light generating means in response to an electric signal outputted from a photoelectric conversion means. SOLUTION: An input optical signal is given to an optical amplifier 1, in which the signal is amplified up to a luminous intensity required for the operation. The input optical signal is converted into an electric signal by a photoelectric converter 2 to directly drive a luminous intensity modulator 3. On the other hand, the luminous intensity modulator 3 receives a continuous light from a continuous wave light source 4 and applies intensity modulation in response to the electric signal to provide an output. When the input optical signal is subjected to intensity modulation, an output optical signal intensity of the luminous intensity modulator 3 changes stepwise with respect to the input optical signal.  Thus, even when the amplitude of an input electric signal obtained by applying photoelectric conversion to amplitude noise of the input optical signal is somewhat fluctuated, the intensity of an output optical signal is almost unchanged.
